Near El Paso, Texas, the train travels right alongside the US-Mexico border wall, sometimes coming within 40 feet of it, with Ciudad Juarez, Mexico on the other side. Here, the train also runs alongside the Rio Grande river. This occurs during the day in both directions, making it one of the journey's most unique viewing experiences. The border wall is on your left when heading toward Los Angeles (westbound), and on the right when heading toward New Orleans (eastbound).
